What Schedule D (Form 1040) 2019 Is For
The IRS Schedule D (Form 1040) (2019) is used to report capital gains and losses from the sale or exchange of capital assets, such as stocks, bonds, mutual funds, exchange-traded funds, real estate, and cryptocurrency. It helps taxpayers calculate the amount of capital gains tax they owe or determine whether they can deduct capital losses from their ordinary income. The form separates short-term capital gains and long-term capital gains, since each is taxed at a different tax rate based on taxable income and filing status.
Schedule D also accounts for net capital gains, net investment income, and adjustments, such as the net investment income tax for higher earners. Taxpayers use this form to ensure they follow Internal Revenue Service reporting rules, accurately pay capital gains taxes, and offset gains with losses when possible. Consulting a tax professional or financial advisor can help filers determine their cost basis, minimize capital gains taxes, and utilize tax-advantaged accounts to lower their overall tax liabilities.
When You’d Use Schedule D (Form 1040)
Taxpayers use Schedule D (Form 1040) when they sell or exchange capital assets such as stocks, mutual funds, real estate, or cryptocurrency that result in capital gains or capital losses. It is required if they received capital gain distributions, have carryover losses from previous tax years, or need to report short-term or long-term gains. Filers must also use it when amending a tax return to correct cost basis errors or add missing transactions. The form ensures that all profits and losses are correctly reported to the Internal Revenue Service and that taxpayers pay the correct amount of capital gains taxes based on their income and filing status.
Key Rules or Details for 2019
For the 2019 tax year, short-term capital gains were taxed as ordinary income at rates ranging from 10% to 37%, while long-term capital gains were taxed at 0%, 15%, or 20%, depending on taxable income and filing status. Taxpayers could deduct up to $3,000 ($1,500 if married filing separately) of net capital losses against ordinary income, carrying any remaining losses forward to future years. Most investment sales required reporting through Form 8949 before totals were transferred to Schedule D, and high-income taxpayers were subject to a 3.8% net investment income tax on certain gains.

Step-by-Step (High Level)
Filing Schedule D involves summarizing all capital transactions and transferring totals to Form 1040.
Step 1: Gather Documents
The taxpayer should collect Forms 1099-B and 1099-S, as well as records showing the purchase dates, sales prices, and cost basis for all sold assets.
Step 2: Complete Form 8949
Each sale or exchange must be listed on Form 8949, including the purchase and sale dates, proceeds, cost basis, and any adjustments.
Step 3: Transfer Totals to Schedule D
Totals from Form 8949 are carried to Schedule D—short-term transactions go in Part I, long-term in Part II. Mutual fund distributions and capital loss carryovers must also be considered.
Step 4: Calculate the Net Gain or Loss
The taxpayer combines short-term and long-term results in Part III to find the overall net capital gain or net capital loss. If there is a loss, up to $3,000 may offset ordinary income.
Step 5: Attach to Form 1040
After calculations, Schedule D is attached to Form 1040, and totals are transferred to the appropriate lines of the tax return.
Common Mistakes and How to Avoid Them
Taxpayers frequently make preventable errors when reporting capital gains and losses on Schedule D. Understanding these common issues can help ensure accurate reporting, prevent IRS notices, and avoid unnecessary tax liabilities.
- Using the incorrect cost basis: Some filers miscalculate their cost basis, resulting in overpayment or underpayment of taxes. Each cost basis must include the purchase price, brokerage commissions, and any reinvested dividends or adjustments.
- Misclassifying holding periods: Many taxpayers confuse short-term and long-term holdings. Assets must be held for more than one year to qualify for favorable long-term capital gains tax rates under federal income tax rules.
- Forgetting to report all transactions: Overlooking sales from multiple brokerage accounts—or ignoring wash sales—can result in missing income and potentially lead to IRS correspondence or penalties.
- Ignoring cryptocurrency transactions: Many forget that the Internal Revenue Service treats digital currency sales as taxable transactions of property. All realized cryptocurrency gains or losses must be reported to avoid compliance issues.
Accurate recordkeeping, complete transaction reporting, and correct classification of capital assets help taxpayers stay compliant and ensure smooth IRS processing of Schedule D.

What Happens After You File
After Schedule D is submitted, the Internal Revenue Service compares the reported capital gains and losses with information from Forms 1099-B, which brokers issue. If all amounts match, the return is processed, and refunds are typically issued within 21 days for e-filed returns or about six to eight weeks for mailed filings. If mismatches occur, the IRS may send a CP2000 notice proposing changes. Taxpayers should keep supporting documents for at least three years in case of review or future amendments.
